4.4 Connection of the Sensor
For normal operating the sensor is connected via a M12 sensor connector (3 poles).
A suitable cable can be delivered optionally (lengths: 2 m/5 m/10 m). A shielding cable
is not necessary for short distances. We recommend a shielding for longer length
(> 30 m) or in rough industrial environments.
For the service a special cable (5 poles) is required. Using the additional lines it is
possible to configure the sensor and to adapt it to customized specifications. Do not
connect unused lines!
Use the service lines only in combination with the ABD Monitor for the
Air Bubble Detektor (delivered on request). Otherwise, the sensor could be
damaged.

4.5 Settings/ABD Monitor
A computer in connection with the ABD monitor (consisting of USB data converter, M12
sensor cable, USB cable, CD with software ABD monitor, operating instructions ABD
monitor) is required for settings or for diagnostic purposes.
The sensor can be customised via parameters:
• Bubble sensitivity
• Reaction time/ hold time of the output/ output states
• internal regulation, e.g. to optimise the behaviour in case of pressure fluctuations
